Each CPE device has a unique DPID (Datapath Identifier). It is a 64-bit number that is generated based on a unique characteristic of the CPE device, such as the MAC address of the WAN0 interface or a serial number.
To use a CPE device, you must first create an entry for it in the web interface, and then connect the device itself to the orchestrator. Alternatively, you can connect the device to the orchestrator (in this case, it is displayed in the web interface with the Unknown status) and then create an entry. In both cases, the entry is associated with the device based on its DPID.
Two main scenarios exist for registering CPE devices: Zero Touch Provisioning (ZTP) or with additional configuration. Additional configuration includes, for example, assigning static IP addresses and creating routes, uploading security certificates, and generating tokens.
The CPE device is configured as follows:
To automatically configure a CPE device over the internet, you must configure public IP addresses of the orchestrator, controller, and SD-WAN gateways. NAT is supported for the following interfaces as an alternative to public IP addresses:
